What is bullshit is all the people that have fallen into the Republican's trap of blaming the immigrants for everything. Damn near every economist worth two shits will tell you, those immigrants, both illegal and legal, give more to the economy than they take. The classic example is the bricklayer, and the "immigrant" that is hired to mix the cement and carry the bricks. In so doing it allows the bricklayer to spend more time doing what he was trained to do, lay bricks. Those immigrants increase productivity and earnings, every study ever done has borne that out. Like this one,^^^ Complete bullshit.
Smith, Mises, Mill--three different economic perspectives, all of them supported free and open borders. Karl Marx, he was the one that demanded strong borders and shutting out immigrants. Free markets require open borders, let the market take care of it, and the reality is, it usually does. When the economy is hurting, like after the 2008 crash, immigration drops to almost nothing. When it is booming, they come. Government actions, walls, restrictions, are like pissing in the wind and have little effect. Time to open the borders and let the "free market" take care of it.
Besides, the primary driving force behind the increase in the number of college graduates in this nation is not student loans or federal financial aide. It is immigration, as the force of that immigration on depressing wages at the low end of the scale has sufficiently motivated Americans to get a damn degree. You, more than anyone, should appreciate that.
